Answer:
The numbers are: 1 and 3.
Step-by-step explanation:
Let the first number be
and the second number be
.
Given: The difference between twice the number and the second number is
. writing this mathematically,
![$ 2x - y = -1 $](https://tex.z-dn.net/?f=%24%202x%20-%20y%20%3D%20-1%20%24)
From the second statement we get:
![$ 2y + 3x = 9 $](https://tex.z-dn.net/?f=%24%202y%20%2B%203x%20%3D%209%20%24)
Solving for
and
we get:
![$ x = 1 $](https://tex.z-dn.net/?f=%24%20x%20%3D%201%20%24)
and ![$ y = 3 $](https://tex.z-dn.net/?f=%24%20y%20%3D%203%20%24)
Thus the first number is 1 and the second number is 3.

x=1/2 I'm not sure it may be wrong
Answer:
The slope is 4
The y-intercept is 3 OR (0, 3)
Step-by-step explanation:
Points on the graph: ( -1, -1) and (0,3)
Slope:
m=(y2-y1)/(x2-x1)
m=(3+1)/(0+1)
m=4/1
m = 4
Point slope-intercept:
y - y1 = m(x - x1)
y + 1 = 4(x + 1)
y + 1 = 4x + 4
y = 4x + 3
